ABSTRACT:
A building construction comprising spaced parallel structural members, such as rolled steel beams and girders, forming a plurality of horizontally disposed structural bays in which the compression flanges of the girders are restrained against lateral displacement or buckling under compressive loads by concrete joists having notched end portions, especially during construction and prior to hardening of concrete poured thereover to form floor slabs. The joists are supported by, and extend transversely between, the girders. Adjacent end portions of the joists are connected to each other to form continuous lines of tension or compression ties at selected intervals along the girders. In a preferred embodiment, the continuous ties terminate at horizontal trusses formed at the end of a row of bays by at least one diagonally disposed truss member, such as a cable.
